The danger here is the possibility of the impeller blades breaking off, mainly due to dry rot. Once the impeller blades have taken a set, and you turn them over, this risk increases. Now, as you happily run down the lake, enjoying yourself, one or more of the impeller blades break off…. Virtually all tiller steer outboards (at least the ones we are discussing) DO NOT have an over heat warning system. Now as you happily run along, the water pump fails to do it’s job, and the motor suddenly overheats. You then begin to notice that the motor has lost some power, and probably doesen’t sound like it normally does. You stop to look back at the water pump/ exaust discharge, and see no water comimng out! Oh crap, you just ruined your powerhead… Is it worth it??
